1·Once it has arrived at the airport and enters onto the tarmac, it can fold down its electrically powered wings, engage its rear-facing propellor and take off down the runway.
一旦它抵达机场停机坪，它就可以展开翅膀，利用其后面的螺旋桨在跑道上起降。
2·Equipped to float with impermeable canvas skirts, these tanks were to propel themselves to the beach with an AD hoc propellor and then resume normal operation.
这些坦克车下截设有不透水帆布围裙，以便漂浮，并特设螺旋桨，以便向海滩推进，登陆之后即可照正常操作。
3·The guidance system consisted of propellor in the nose.
制导系统包括螺旋桨的鼻子。
4·The outer wings, tail and propellor have been removed from the aircraft.
这架飞机的外翼、机尾和螺旋桨已经被拆除了。
5·These analysis results are references for both new type of structure design and the research on characters of fluid dynamics of propellor.
分析结果可供变螺距螺旋桨的新型结构设计和流体动力特性研究参考。
